I have made a tool handle for some carbide insert tools I bought online.Here are the tools:

(202.53 KiB)

They sell a handle for them, which I bought:

(186.82 KiB)

However I was not impressed with it, its made from an aluminium tube and uses 2 grub screws to hold the shaft of the tool. It is so light that I find it a has a bad vibration problem, so I looked round for alternative possibilities. I found what is sold as collet extension that uses ER20 collets.

(115.97 KiB)

I got a 12 mm collet for it:

(198.05 KiB)

And a length of steel tube with a 20mm ID:

(188.98 KiB)

I drilled and tapped 2 holes for grub screws to hole the collet holder in place:

(166.5 KiB)

I tried this out and it was a major improvement over the bought handle, so to make it more comfortable to use I bought a length of foam sold for the handles on gym equipment:

(196.65 KiB)

I then turned a wooden knob to fit in the other end of the tube:

(115.19 KiB)

I drilled a hole for a screw to hold it in place:

(116.89 KiB)

Then I slid the foam over the pipe and fitted a screw:

(113.13 KiB)

Here is the finished tool, it works well and is quite nice in the hand as well:

Nice job. I’ve also made my own tools and handles. I use thick wall alloy tube or wood with ER20 chucks. With the tubular ones you can easily add a steel slug in the handle to increase the weight but I’ve not found it necessary so far.
